Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, specifically a drawing frame with a built-in dust collection device. Background Technology
[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments, reducing weight unevenness, straightening and parallelizing the fibers in the sliver, reducing hooks, ensuring the fineness meets specifications, and uniformly mixing different types or qualities of raw materials to achieve the specified mixing ratio. Drawing frames are broadly classified into roller drawing frames and carding frames according to their drafting mechanism. Cotton spinning drawing frames come in various types, including single-eye, double-eye, and four-eye. Although drawing frames have built-in fans that can absorb short fibers and dust in the sliver channel during operation, short fibers, dust, and cotton residue outside the channel cannot be removed and must be removed by additional devices. Therefore, it is evident that modern drawing frames still have some problems.
[0003] Existing drawing frames generate short fibers, dust, and cotton residue during use. When dealing with these, workers use handheld air guns to remove the dust, which can easily cause the dust to blow back and forth, leading to secondary pollution and increasing the workload for workers. This is also inconvenient for workers to use. Utility Model Content
[0004] The purpose of this invention is to provide a drawing frame with a built-in dust collection device to solve the problem mentioned in the background art where workers use a handheld air gun to remove dust when processing short fibers, dust, and cotton residue, which easily causes the dust to blow back and forth, resulting in secondary pollution.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawing frame with a built-in dust collection device, comprising a drawing frame body, an installation box fixedly connected to the top of the drawing frame body, a transmission box fixedly connected to the outer wall of the installation box, a blower box fixedly connected to the top of the transmission box, an air duct fixedly connected to the top of the blower box, a transmission assembly disposed inside the transmission box, a feed rod fixedly connected to both ends of the transmission assembly, a dust collection hood fixedly connected to the outer wall of the transmission box, and the dust collection hood being located on one side of the feed rod, a connecting pipe fixedly connected to the outer wall of the dust collection hood, and the connecting pipe penetratingly connecting to the bottom of the blower box.
[0006] Preferably, a control box is fixedly connected to one side of the outer wall of the drawing frame body, and a feed inlet is provided on the top of the drawing frame body.

[0008] Preferably, the transmission assembly includes a second transmission rod, which is installed through the inside of the transmission box. A second transmission gear is fixedly connected to the outer wall of the transmission box, and a transmission rack meshes with the outer wall of the first transmission gear.
[0009] Preferably, a connecting rod is fixedly connected to the outer wall of the conveying rod, a telescopic rod is slidably connected to the top end of the connecting rod, and a push plate is fixedly connected to the top end of the telescopic rod.
[0010] Preferably, a return spring is fixedly connected to the inner bottom wall of the connecting rod, and the top end of the return spring is fixedly connected to the bottom of the telescopic rod.
[0011] Preferably, a collection rack is slidably connected inside the wind turbine box, and a filter screen is fixedly connected inside the collection rack.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By connecting the air duct to the external dust collection device, the suction power of the external dust collection device is delivered to the dust collection hood through the air box and connecting pipe. The dust collection hood can be used to vacuum the outside of multiple material conveying rods, thus avoiding the problem of secondary pollution caused by workers using handheld air guns to remove dust, which would result in the dust being blown back and forth. It also reduces the workload of workers and improves the efficiency of dust removal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] A drawing frame with a built-in dust collection device includes a drawing frame body 1. A mounting box 4 is fixedly connected to the top of the drawing frame body 1. A transmission box 5 is fixedly connected to the outer wall of the mounting box 4. A blower box 17 is fixedly connected to the top of the transmission box 5. An air duct 18 is fixedly connected to the top of the blower box 17. A transmission assembly is provided inside the transmission box 5. A feed rod 12 is fixedly connected to both ends of the transmission assembly. A dust collection hood 21 is fixedly connected to the outer wall of the transmission box 5 and is located on one side of the feed rod 12. A connecting pipe 22 is fixedly connected to the outer wall of the dust collection hood 21 and is connected through the bottom of the blower box 17.
[0024] When the main body 1 of the drawing frame is in use, the transmission assembly can drive the feed rod 12 to rotate. When the feed rod 12 rotates, it can transport the cotton sliver and assist in transporting the cotton sliver into the interior of the main body 1 of the drawing frame for drawing. When the main body 1 of the drawing frame is stopped, the air duct 18 is connected to an external dust collection device. The suction power of the external dust collection device is transported to the dust collection hood 21 through the air box 17 and the connecting pipe 22. The dust collection hood 21 can collect dust from the outside of multiple feed rods 12, thereby avoiding the problem of secondary pollution caused by workers using handheld air guns to remove dust, and reducing the workload of workers and improving the efficiency of dust removal.
[0025] Furthermore, a control box 3 is fixedly connected to one side of the outer wall of the main body 1 of the drawing frame, and a feed inlet 2 is provided on the top of the main body 1 of the drawing frame.
[0026] The operation of the drawing frame body 1 can be controlled by the control box 3. When the drawing frame body 1 is running, the cotton sliver can be put into the interior of the drawing frame body 1 through the feed port 2 for drawing.
[0027] Furthermore, a servo motor 6 is fixedly connected inside the mounting box 4, and a first transmission rod 7 is fixedly connected to the output end of the servo motor 6. A first transmission gear 8 is fixedly connected to the outer wall of the first transmission rod 7. The transmission assembly includes a second transmission rod 10, which is installed through the inside of the transmission box 5. A second transmission gear 11 is fixedly connected to the outer wall of the transmission box 5, and a transmission rack 9 meshes with the outer wall of the first transmission gear 8.
[0028] The servo motor 6 operates, which drives the first transmission rod 7 to rotate. When the first transmission rod 7 rotates, it drives the second transmission rod 10 to rotate through the first transmission gear 8, the transmission rack 9, and the second transmission gear 11. When the second transmission rod 10 rotates, it drives the feeding rods 12 on both sides of the transmission box 5 to rotate. The feeding rods 12 can be used to feed the cotton strips.
[0029] Furthermore, a connecting rod 13 is fixedly connected to the outer wall of the conveying rod 12, a telescopic rod 14 is slidably connected to the top of the connecting rod 13, a push plate 16 is fixedly connected to the top of the telescopic rod 14, and a return spring 15 is fixedly connected to the inner bottom wall of the connecting rod 13, with the top of the return spring 15 fixedly connected to the bottom of the telescopic rod 14.
[0030] When the cotton sliver is conveyed by the feed rod 12, the elastic force of the return spring 15 can drive the connecting rod 13 to reset inside the telescopic rod 14, thereby adjusting the distance of the push plate 16 so that the push plate 16 abuts against the cotton sliver, ensuring that the cotton sliver remains taut during conveying, thereby improving the quality of the cotton sliver during sizing and facilitating subsequent processing by the staff.
[0031] Furthermore, a collection rack 19 is slidably connected inside the wind turbine box 17, and a filter screen 20 is fixedly connected inside the collection rack 19.
[0032] When vacuuming the outside, the air entering the air chamber 17 can be filtered through the collection rack 19 and the filter screen 20. After filtration, the collection rack 19 can be slid out from the inside of the air chamber 17, making it easy for staff to remove the short lint, dust and cotton residue stuck to the top of the collection rack 19 and the filter screen 20.
[0033] Working principle: When the main body 1 of the drawing frame is in use, the servo motor 6 runs, which drives the first transmission rod 7 to rotate. The rotation of the first transmission rod 7 drives the second transmission rod 10 to rotate via the first transmission gear 8, transmission rack 9, and second transmission gear 11. The rotation of the second transmission rod 10 drives the conveying rods 12 on both sides of the transmission box 5 to rotate. The rotation of the conveying rods 12 conveys the cotton sliver, assisting in its delivery into the drawing frame main body 1 for drawing. During the conveying of the cotton sliver via the conveying rods 12... The elastic force of the return spring 15 can drive the connecting rod 13 to reset inside the telescopic rod 14, thereby adjusting the distance of the push plate 16 so that the push plate 16 abuts against the cotton sliver, ensuring that the cotton sliver remains taut during conveying. When the main body 1 of the drawing machine is stopped, the air duct 18 is connected to the external dust collection device. The suction of the external dust collection device is conveyed to the dust collection hood 21 through the air box 17 and the connecting pipe 22. The dust collection hood 21 can be used to collect dust from the outside of multiple feed rods 12. The air entering the air box 17 can be filtered through the collection rack 19 and the filter screen 20.
